The Failed Login Attempts plugin gives you an overview of your failed logins, but you can make it even better by applying a simple override. The override provides a link to more information about who has tried to log in, and you can therefore use other extensions to block the user or take measures.

With the Failed Login Attempts extension installed, you can easily track failed logins on your site, but you can go even further by doing an override to the "default.php" file in your admin template. You can see where the origin of the IP address is coming from by clicking the link. The only downside is that you, on extension updates, get a warning to check the override. 

But if you update the override, the warning disappears.

1. Go to System Administrator Templates  Atum Details and Files

 Now you go into Template and Details of the given template

Now you will go into the place where you create overrides.

Click on "Create overrides" → com_failedloginattempts from the components 

The orignial code is:

In Joomla 4, we were introduced to “subforms”, which are great for creating more user-friendly fields for your articles or page, containing the fields in the subform.

The problem is that when you create a subform, the fields in the subform are divided by a comma. This doesn’t look good on your pages, so to solve this problem, we can override the default subform of Joomla.

To achieve this, you need to create an override for the subform. This can be done by creating a new file in the html folder of your template. Here you can read more about "how do I get a Subform to look better".

Go to System > Site Templates.

Choose your template by selecting it. In this example, we will use the default J4 template “Cassiopeia”, so go into “Cassiopeia Details and Files”.

Select “Create Overrides” > Plugins > fields > subform

You need to open the file in the Joomla Editor located in the “html” folder. Navigate to the file “subform.php” in the folder ”/templates/cassiopeia/html/plg_fields_subform”. The file should look like this:

<?php
/**
 * @package     Joomla.Plugin
 * @subpackage  Fields.Subform
 *
 * @copyright   (C) 2019 Open Source Matters, Inc. <https://www.joomla.org>
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */

use Joomla\Component\Fields\Administrator\Helper\FieldsHelper;

defined('_JEXEC') or die;

if (!$context || empty($field->subform_rows))
{
	return;
}

$result = '';

// Iterate over each row that we have
foreach ($field->subform_rows as $subform_row)
{
	// Placeholder array to generate this rows output
	$row_output = array();

	// Iterate over each sub field inside of that row
	foreach ($subform_row as $subfield)
	{
		$class   = trim($subfield->params->get('render_class', ''));
		$layout  = trim($subfield->params->get('layout', 'render'));
		$content = trim(
			FieldsHelper::render(
				$context,
				'field.' . $layout, // normally just 'field.render'
				array('field' => $subfield)
			)
		);

		// Skip empty output
		if ($content === '')
		{
			continue;
		}

		// Generate the output for this sub field and row
		$row_output[] = '<span class="field-entry' . ($class ? (' ' . $class) : '') . '">' . $content . '</span>';
	}

	// Skip empty rows
	if (count($row_output) == 0)
	{
		continue;
	}

	$result .= '<li>' . implode(', ', $row_output) . '</li>';
}
?>

<?php if (trim($result) != '') : ?>
	<ul class="fields-container">
		<?php echo $result; ?>
	</ul>
<?php endif; ?>

Now Change the code in line 56 from this:

	$result .= '<li>' . implode(', ', $row_output) . '</li>';

To this:

	$result .= '<li>' . implode('<span class="field-divider">,</span> ', $row_output) . '</li>';

Then simply put this in "user.css":

.field-divider { display: none; }
